Eskom confirms Koeberg nuclear reactor trip, says safety not at risk
'Eskom is currently able to supply sufficiently without the need for load-shedding': spokesperson
Eskom confirmed on Wednesday that unit one at the Koeberg nuclear power reactor “tripped” on Monday afternoon.
The power utility said there were “no nuclear safety concerns” as a result.
“Eskom can confirm that Koeberg unit one reactor tripped at 4.30pm on Monday due to a fault on the electrical breaker to one of the primary coolant pumps. Eskom can confirm that the reactor was then safely shut down by the operators, in compliance with the operating procedure.
“Initial fault-finding ruled out any concerns on the primary pump or the motor itself. There are no nuclear safety concerns. By midmorning yesterday [Tuesday] the cause of the trip was confirmed to be a faulty electrical protection relay, which tripped the primary motor,” Eskom said in a statement.
Further assessments needed to be done before the unit could be returned to service, which will be “during the weekend”, it said.
Asked about the implications of the incident, particularly in terms of power supply and possible rotational power outages, spokesperson Sikonathi Mantshantsha told TimesLIVE: “Eskom is currently able to supply sufficiently without the need for load-shedding.”
